Full Definition
Acute lymphoblastic leukemia (ALL) is the most prevalent form of childhood cancer, accounting for approximately 25% of all pediatric malignancies. It affects lymphoblasts, immature white blood cells that fail to develop properly and accumulate in the bone marrow and blood. ALL has distinct subtypes and treatment protocols that differ significantly from adult leukemias, making precise terminology critical in pediatric oncology documentation.
